I generally try to look my opponents in the eye, I think in our culture it's not generally done so much because it can be misconstrued as rude which really throws people off sometimes. When I started naginata, we were taught to always be looking our opponent in the eye which can be hard if you're not used to it, but now it's not so bad. I find now when I'm sparring in karate, I do look into my opponents eyes but also let my peripheral vision take over some too.

A real man does not think of victory or defeat. He plunges recklessly towards an irrational death. By doing this, you will awaken from your dreams.
